FIG. 6 is a diagram of a protective fender 31 according to the first embodiment of the present invention. FIG. 7 is a diagram of a locking component 351 according to the first embodiment of the present invention. FIG. 8 is a sectional diagram of the child car safety seat 100 along an A-A line shown in FIG. 3 according to the first embodiment of the present invention. FIG. 9 is an enlarged diagram of a B portion of the child car safety seat 100 shown in FIG. 8 according to the first embodiment of the present invention. FIG. 10 is a diagram of a connecting portion 21 shown in FIG. 3 according to the first embodiment of the present invention. As shown in FIG. 1 and FIG. 2, the child car safety seat 100 includes a seat body 10 and a base 20 and two lateral shock absorbers 30. The seat body 10 is installed on the base 20 for accommodating a child. The two lateral shock absorbers 30 are disposed on two sides of the base 20. The two lateral shock absorbers 30 can be operated to switch from a folded state as shown in FIG. 1 to an unfolded state as shown in FIG. 2 relative to the base 20 when the child car safety seat 100 is installed on a car seat. During a side impact collision, the child car safety seat 100 can collide with a car body by the lateral shock absorbers 30, so as to transfer a side impact to the base 20 and away from the child, which can achieve a purpose of reducing a risk of injury or death of the child due to the side impact and provide enhanced protection for the child. However, the number of the lateral shock absorber 30 is not limited to this embodiment. For example, in another embodiment, the child car safety seat also can include only one lateral shock absorber disposed on one side of the base.

The two lateral shock absorbers 30 have identical structures. For simplicity, one of the two lateral shock absorbers 30 at one side is introduced as follows. As shown in FIG. 3 to FIG. 5, the lateral shock absorber 30 includes the protective fender 31, a resilient component 33 and a locking mechanism 35. An end of the protective fender 31 is pivoted to the base 20, so that the protective fender 31 is pivotally switchable between the folded state and the unfolded state relative to the base 20. The resilient component 33 is for biasing the protective fender 31 to switch to the unfolded state. The locking mechanism 35 is for selectively engaging with the protective fender 31 to restrain the protective fender 31 from switching to the unfolded state or from disengaging from the protective fender 31 to allow the protective fender 31 to switch to the unfolded state by the resilient component 33 when the protective fender 31 is located in the folded state.

In order to facilitate pivotal connections of the ends of the two protective fenders 31 and the base 20, the base 20 includes the two connecting portions 21 and a base body. The two connecting portions 21 protrude from the base body. Preferably, the two connecting portions 21 can protrude from end portions of two of four corners of the base body. The two protective fenders 31 are pivotally connected to the two connecting portions 21, respectively. Furthermore, the protective fender 31 and the corresponding connecting portion 21 are arranged side by side when the protective fender 31 is in the folded state. Preferably, a first protrusion 311 can be formed on a lower end of the protective fender 31, and a second recess 213 can be formed on the connecting portion 21 and located at a position corresponding to the first protrusion 311, so as to facilitate the protective fender 31 to switch to the folded state by engagement of the first protrusion 311 and the second recess 213. Besides, the first protrusion 311 can increase an area of the lower end of the protective fender 31, so as to provide a better side buffering effect during a side impact collision.

Preferably, in this embodiment, the resilient component 33 can be a torsional spring disposed on a pivoting shaft of the protective fender 31 and abutting between the protective fender 31 and the connecting portion 21 to facilitate the protective fender 31 to switch to the unfolded state. More preferably, in this embodiment, a first recess 211 can be formed on an upper end of the connecting portion 21 for installing an end of the torsional spring to facilitate operation of the torsional spring. However, the type and the configuration of the resilient component 33 are not limited to this embodiment. The resilient component 33 also can be any other resilient element and disposed in a different manner.

As shown in FIG. 5 and FIG. 6, the locking mechanism 35 includes the locking component 351 and a recovering component 353. A locking hole 355 is formed on the protective fender 31. An installing hole 357 is formed on the connecting portion 21 of the base 20. The locking component 351 and the recovering component 353 are installed inside the installing hole 357. Specifically, in this embodiment, the recovering component 353 can abut between a bottom wall of the installing hole 357 and the locking component 351 for biasing the locking component 351 to engage with the locking hole 355 to restrain movement of the protective fender 31. However, it is not limited to this embodiment. For example, in another embodiment, the locking hole can be formed on the connecting portion for installing the locking component and the recovering component, and the installing hole can be formed on the protective fender. Furthermore, understandably, in another embodiment, the child car safety seat can further include an operating component connected to the locking mechanism for driving the locking mechanism to disengage from the protective fender. For example, the operating component can be connected to the locking component for driving the locking component to disengage from the locking hole to allow movement of the protective fender.

Preferably, in this embodiment, the recovering component 353 can be a compression spring. However, it is not limited thereto.

Understandably, in another embodiment, the locking mechanism can further include a restraining portion disposed inside the installing hole for restraining a displacement distance of the locking component to prevent disengagement of the locking component and the installing hole caused by the recovering component.

As shown in FIG. 5 to FIG. 10, in this embodiment, the locking mechanism further includes a driving pin 359. A through hole 352 is formed on the locking component 351. A long slot 40 is formed on the connecting portion 21 for allowing the driving pin 359 to pass therethrough. The driving pin 359 is inserted into the through hole 352 by passing through the long slot 40 to be fixed on the locking component 351. The driving pin 359 can be operated via the long slot 40 to drive the locking component 351 to disengage from the locking hole 355, so as to allow the protective fender 31 to switch from the folded state to the unfolded state. Preferably, in this embodiment, the driving pin 359 can be made of metal material and formed in a circular column, and a shape of the through hole 352 can be corresponding to a shape of the driving pin 359. However, the material and the shape of the driving pin 359 are not limited to this embodiment. For example, in another embodiment, the driving pin also can be formed in a square or rectangular column. Furthermore, the structure and the configuration of the driving pin are not limited to this embodiment. For example, in another embodiment, the driving pin can be configured to prevent the disengagement of the locking component and the locking hole by insertion of the driving pin into the through hole and to allow the disengagement of the locking component and the locking hole by removal of the driving pin from the through hole.

Besides, understandably, in another embodiment, the child car safety seat can further include two releasing portions disposed on a bottom portion of the seat body. The releasing portion is for driving the driving pin to disengage the locking component from the locking hole when the seat body is installed on the base, which simplifies operation of the child car safety seat. Specifically, the releasing portion can be a protrusion disposed on the bottom portion of the seat body and located at a position corresponding to the long slot, so that the protrusion can operate the driving pin via the long slot to disengage the locking component from the locking hole to allow the protective fender to switch to the unfolded state by the resilient component when the seat body is installed on the base, which brings convenience in use.

Furthermore, as shown in FIG. 5 to FIG. 7, a first guiding inclined surface 50 is formed on a lower end of the protective fender 31. A second guiding inclined surface 60 is formed on the locking component 351. The locking component 351 is driven by cooperation of the first guiding inclined surface 50 and the second guiding inclined surface 60 and the recovering component 353 to engage with the locking hole 355 when the protective fender 31 switches from the unfolded state to the folded state.

As shown in FIG. 1 to FIG. 10, operational principle of the child car safety seat 100 of this embodiment is provided as follows.

When the child car safety seat 100 is not in use, the protective fender 31 can be operated to pivotally switch to the folded state relative to the base 20 to save occupied space of the child car safety seat 100. During the aforementioned process, the resilient component 33 can be resiliently deformed, and the locking component 351 can be driven by cooperation of the first guiding inclined surface 50 and the second guiding inclined surface 60 and the resiliently deformed recovering component 353 to engage with the locking hole 355, so as to restrain the protective fender 31 in the folded state. Furthermore, when the protective fender 31 is in the folded state, the protective fender 31 and the connecting portion 21 are arranged side by side due to the engagement of the second recess 213 and the first protrusion 311.

When the child car safety seat 100 is in use, the protective fender 31 can be operated to pivotally switch from the folded state to the unfolded state relative to the base 20 to reduce a side impact on the child during a side impact collision. Specifically, the driving pin 359 can be operated via the long slot 40 to drive the locking component 351 to disengage from the locking hole 355 for allowing the protective fender 31 to leave away from the folded state. At this moment, the resiliently deformed resilient component 33 can drive the protective fender 31 to pivotally switch from the folded state to the unfolded state relative to the base 20. Therefore, during a side impact collision, the child car safety seat 100 can collide with the car body by the protective fender 31 of the corresponding lateral shock absorber 30, so as to transfer a side impact to the base 20 and away from the child, which can achieve the purpose of reducing the risk of injury or death of the child due to the side impact and provide the enhanced protection for the child.

Please refer to FIG. 11 to FIG. 13. FIG. 11 is a schematic diagram of a child car safety seat in a using state without illustrating the seat body 10 according to a second embodiment of the present invention. FIG. 12 is a partial diagram of the child car safety seat shown in FIG. 11 according to the second embodiment of the present invention. FIG. 13 is another partial diagram of the child car safety seat shown in FIG. 11 at another view according to the second embodiment of the present invention. As shown in FIG. 11 to FIG. 13, different from the child car safety seat of the first embodiment, in this embodiment, the seat body 10 includes two engaging portions, which is not shown in figures, and two engaging slots are formed on two front corners of the base 20, which are not indicated by any numeral, so that the seat body 10 can be detachably installed on the base 20 by engagement of the engaging portions and the engaging slots. The two locking mechanisms 35 are disposed on the base 20. The two locking mechanisms 35 can be operated by the seat body 10 to sequentially switch to a first state and a second state while the seat body 10 is installed on the base 20. When the two locking mechanisms 35 are in the first state, the two protective fenders 31 are allowed to switch to the unfolded state by the two resilient components 33, which can achieve a purpose of preventing a situation in which a caregiver forgets to unfold the protective fender 31. When the two locking mechanisms 35 are in the second state, the two locking mechanisms 35 can engage with the two protective fenders 31 switching from the unfolded state to the folded state.

The two locking mechanisms 35 have identical structures. For simplicity, one of the two locking mechanisms 35 at one side is introduced as follows. The locking mechanism 35 includes a locking assembly 3 a, an abutting component 3 b and an abutting block 3 c connected to the abutting component 3 b. Preferably, the abutting block 3 c can be disposed inside the engaging slot. However, it is not limited thereto. The locking assembly 3 a is for engaging with the protective fender 31 to restrain movement of the protective fender 31. The locking assembly 3 a includes two protruding lugs 36 a. The abutting component 3 b includes a first abutting portion 31 b detachably abutting against the two protruding lugs 36 a. The abutting component 3 b can be driven by the abutting block 3 c to press the two protruding lugs 36 a to drive the locking assembly 3 a to move to a releasing state to disengage from the protective fender 31 when the abutting block 3 c is pressed downwardly by the engaging portion of the seat body 10 to a first position. At this moment, the protective fender 31 can switch to the unfolded state by the resilient component 33, and an included angle between the protective fender 31 in the unfolded state and a lateral surface of the base 20 can be substantially 100 degrees. However, it is not limited to thereto. The included angle between the protective fender 31 in the unfolded state and the lateral surface of the base 20 can be substantially from 90 to 145 degrees.

Afterwards, the abutting component 3 b can be further driven by the abutting block 3 c to disengage the first abutting portion 31 b from the two protruding lugs 36 a and to drive the locking assembly 3 a to a locking state when the abutting block 3 c is pressed downwardly by the seat body 10 from the first position to a second position lower than the first position. At this moment, the protective fender 31 switching from the unfolded state to the folded state can be engaged with and restrained by the locking assembly 3 a in the locking state. However, the number of the protruding lug 36 a is not limited to this embodiment. For example, in another embodiment, the locking mechanism can include only one protruding lug.

Besides, preferably, the locking mechanism 35 can further include a second recovering component 3 e for biasing the abutting block 3 c to recover. Specifically, the second recovering component 3 e can abut between the base 20 and the abutting block 3 c to bias the abutting block 3 c to recover. Furthermore, preferably, the abutting block 3 c and the abutting component 3 b can be integrally formed to extend service lives of the abutting block 3 c and the abutting component 3 b and facilitate operations of the abutting block 3 c and the abutting component 3 b.

In order to ensure that the locking assembly 3 a can be operated to be in the locking state for engaging the protective fender 31 after disengagement of the two protruding lugs 36 a and the first abutting portion 31 b, a range of the movements of the two protruding lugs 36 a can be restrained. Preferably, the abutting component 3 b can further include a second abutting portion 32 b. A vertical distance between the second abutting portion 32 b and the two protruding lugs 36 a is greater than a vertical distance between the first abutting portion 31 b and the two protruding lugs 36 a. The two protruding lugs 36 a abut against the second abutting portion 32 b after the disengagement of the two protruding lugs 36 a and the first abutting portion 31 b, which can effectively restrain the range of the movements of the two protruding lugs 36 a.

As shown in FIG. 11 to FIG. 13, the locking assembly 3 a includes a locking rod 31 a, a pivoting component 35 a and a first recovering component 37 a. The locking rod 31 a includes a locking end 32 a and a connecting end, which is not indicated by any numeral. The locking end 32 a is for engaging with the protective fender 31 to restrain movement of the protective fender 31. The connecting end is pivoted to the pivoting component 35 a. The two protruding lugs 36 a are disposed on two sides of the pivoting component 35 a. The first recovering component 37 a is for biasing the locking rod 31 a to recover to engage with the protective fender 31. Specifically, the locking assembly 3 a further includes a block plate 34 a located between the locking end 32 a and the connecting end, and the first recovering component 37 a abuts between the block plate 34 a and the base 20. In other words, it is required to overcome a resilient force generated by the first recovering component 37 a so that the abutting component 3 b can press the two protruding lugs 36 a.

Furthermore, the locking mechanism 35 further includes a pushing component 3 d disposed beneath the pivoting component 35 a. The pushing component 3 d includes a pushing inclined surface 31 d for abutting a lower end of the pivoting component 35 a, and the pivoting component 35 a is driven by the pushing inclined surface 31 a to pivot to drive the two protruding lugs 36 a to disengage from the first abutting portion 31 b and then to engage with the second abutting portion 32 b. Specifically, a through slot, which is not indicated by any numeral, is formed on the abutting component 3 b. The pivoting component 35 a passes through the through slot.

Operational principle of the child car safety seat of this embodiment is provided as follows.

When the child car safety seat is not in use, the seat body 10 can be detached from the base 20. At this moment, the protective fender 31 can be operated to switch to the folded state relative to the base 20, so that the protective fender 31 can be engaged with and restrained by the locking mechanism 35. At this time, the locking rod 31 a is located at a locking position, and the locking end 32 a of the locking rod 31 a located above the block plate 34 a engages with the protective fender 31. The first abutting portion 31 b abuts against the two protruding lugs 35 a.

When it is desired to use the child car safety seat, the seat body 10 can be installed on the base 20, so that the engaging portion of the seat body 10 press the abutting block 3 c downwardly to the second position via the first position. During a process of the abutting block 3 c moving to the first position, the abutting block 3 c drives the first abutting portion 31 b of the abutting component 3 b to press the two protruding lugs 36 a to drive the pivoting component 35 to move the locking rod 31 a downwardly to disengage from the protective fender 31. At this moment, the protective fender 31 can be driven by the resilient component 33 to switch to the unfolded state.

Afterwards, during a process of the abutting block 3 c moving from the first position to the second position, the abutting block 3 c drives the first abutting portion 31 b of the abutting component 3 b to press the two protruding lugs 36 a to drive the pivoting component 35 to move downwardly to abut against the pushing inclined surface 31 a, so that the pivoting component 35 a can be driven by the pushing inclined surface 31 a to pivot to drive the two protruding lugs 36 a to disengage from the first abutting portion 31 b and then to engage with the second abutting portion 32 b by the first recovering component 37 a. At this moment, the locking rod 31 a is driven to recover to the locking position. Therefore, when it is desired to fold the protective fender 31 at one side, the caregiver can operate the protective fender 31 manually, so that the locking rod 31 a engages with the protective fender 31, which saves the occupied space. In other words, the child car safety seat of this embodiment can not only unfold the protective fender 31 by engagement of the seat body 10 and the base 20 for preventing the situation in which the caregiver forgets to unfold the protective fender 31 but also allow the protective fender 31 switching from the unfolded state to the folded state to be engaged with and restrained by the locking rod 31 a for saving occupied space.

FIG. 24 is an enlarged diagram of a D portion of the child car safety seat shown in FIG. 23 according to the third embodiment of the present invention. As shown in FIG. 14 to FIG. 20, different from the child car safety seats of the aforementioned embodiments, the protective fender 31 of this embodiment includes the driving block 11 a, the supporting block 13 a and a combining assembly 15 a. The driving block 11 a is pivoted to the base 20 and includes a protruding portion 111 a. As shown in FIG. 14, the protruding portion 111 a is biased to pivot upwardly to switch the protective fender 31 to the folded state. When the seat body 10 is not installed on the base 20, the protruding portion 111 a is located at a raising position, so that the protective fender 31 is in the folded state. While the seat body 10 is installed on the base 20, the seat body 10 presses the protruding portion 111 a to pivotally switch the protective fender 31 to the unfolded state. The supporting block 13 a is pivoted to the driving block 11 a. The supporting block 13 a is pivotally connected to driving block 11 a by the combining assembly 15 a and pivotally switchable between a folded position and an unfolded position relative to the driving block 11 a. Preferably, in this embodiment, a pivoting shaft of the supporting block 13 a and the driving block 11 a can be the same as a pivoting shaft of the driving block 11 a and the base 20. However, it is not limited to this embodiment. When the protective fender 31 is in the unfolded state, the supporting block 13 a is located at the unfolded position relative to the driving block 11 a, and the driving block 11 a is located at the unfolded position relative to the base 20. The supporting block 13 a can be operated to pivot to the folded position relative to the driving block 11 a and received inside a lateral portion of the base 20, as shown in FIG. 16 and FIG. 18, so as to save occupied space. However, at this moment, the driving block 11 a is still located at the unfolded position relative to the base 20.

As shown in FIG. 19 and FIG. 20, the combining assembly 15 a includes a pulling plate 151 a, two inserting pins 156 a and a first resilient component 157 a located between the two inserting pins 156 a. Two inserting slots 112 a are formed on the driving block 11 a for allowing the two inserting pins 156 a to pass therethrough. A first pulling slot 152 a and a second pulling slot 153 a are formed on the pulling plate 151 a. A first column 131 a protrudes from the supporting block 13 a and passes through the first pulling slot 152 a. A second column, which is not indicated by any numeral, protrudes from each inserting pin 156 a and passes through the second pulling slot 153 a. The first resilient component 157 a is for biasing the two inserting pins 156 a to recover to engage with the two inserting slots 112 a. The supporting block 13 a is restrained from pivoting relative to the driving block 11 a when the two inserting pins 156 a engage with the two inserting slots 112 a. The supporting block 13 a is allowed to pivot relative to the driving block 11 a when the pulling plate 151 a is operated to disengage the two inserting pins 156 a from the two inserting slots 112 a. Specifically, in this embodiment, the second pulling slot 153 a includes a first side 154 a and a second side 155 a. A length of the second side 155 a is less than a length of the first side 154 a. The two inserting pins 156 a are located at the first side 154 a when the two inserting pins 156 a engage with the two inserting slots 112 a, so as to restrain pivotal movement of the supporting block 13 a relative to the driving block 11 a. Furthermore, the two inserting pins 156 a are located at the second side 155 a when the two inserting pins 156 a disengage from the two inserting slots 112 a, so as to allow the pivotal moment of the supporting block 13 a relative to the driving block 11 a. However, the numbers of the inserting pin 156 a and the inserting slot 112 a are not limited to this embodiment. For example, in another embodiment, the combining assembly also can include one inserting pin and one corresponding inserting slot for allowing or restraining the pivotal movement of the supporting block relative to the driving block.

As shown in FIG. 21 and FIG. 22, the lateral shock absorber further includes a restraining mechanism 36. An end of the restraining mechanism 36 is disposed on the base 20. Another end of the restraining mechanism 36 is movable relative to the driving block 11 a for engaging with the driving block 11 a to restrain the driving block 11 a from being pivotally folded relative to the base 20. In other words, the restraining mechanism 36 can ensure the protective fender 31 to be in the unfolded state even during a side impact collision. Furthermore, the restraining mechanism 36 includes a restraining component 361, a restraining switch 363 and a second resilient component 365. The restraining switch 363 is installed on the base 20. The second resilient component 365 abuts against the restraining component 361 and the base 20. An end of the restraining component 361 is installed on the restraining switch 363, and the restraining switch 363 controls another end of the restraining component 361 to extend outwardly to engage with driving block lla or retract inwardly to disengage from the driving block lla.

Specifically, a restraining slot 364 is formed on the restraining switch 363. The restraining slot 364 includes a first end and a second end. In this embodiment, the first end and the second end can be a closed end and an open end respectively. However, it is not limited thereto. A width of the restraining slot 364 gradually increases from the first end to the second end, and a restraining column 362 protrudes from the restraining component 361 and passes through the restraining slot 364. The restraining component 361 can be driven to engage with the driving block 11 a or disengage from the driving block 11 a by cooperation of the restraining column 362 and the restraining slot 364. In other words, in this embodiment, the end of the restraining component 361 is installed on the restraining switch 363, and the another end of the restraining component 361 is driven to extend outwardly to abut against a lower portion of the driving block 11 a for restraining the driving block 11 a from pivoting to the folded position relative to the base 20 or to retract inwardly to leave apart from the driving block 11 a to allow the driving block 11 a to pivot to the folded position relative to the base 20.

Operational principle of protective fender 31 of this embodiment is provided as follows.

When the protective fender 31 is in the unfolded state, the supporting block 13 a is at the unfolded position relative to the driving block 11 a, and the driving block 11 a is at the unfolded position relative to the base 20. The another end of the restraining component 361 extends outwardly to abut against the lower portion of the driving block 11 a for restraining the driving block 11 a from pivoting to the folded state relative to the base 20. The two inserting pins 156 a are located at the first side 154 a and engage with the two inserting slots 112 a, so as to restrain the pivotal movement of the supporting block 13 a relative to the driving block 11 a. When it is desired to fold the supporting block 13 a relative to the driving block 11 a, the pulling plate 151 can be operated to drive the two inserting pins 156 a to move from the first side 154 a to the second side 155 a. During the aforementioned process, the first resilient component 157 is compressed, and a distance between the two inserting pins 156 a is reduced, so that the two inserting pins 156 a are driven to disengage from the tow inserting slots 112 a to allow the supporting block 13 a to pivot to the folded position to save occupied space. It should be noticed that, after the supporting block 13 a pivots to the folded position, the driving block 11 a is still at the unfold position, i.e., an end of the driving block 11 a with the inserting slots 112 a protrudes from the supporting block 13 a or the lateral surface of the base 20. In order to pivot the driving block 11 a to the folded position relative to the base 20, the restraining switch 363 can be operated to drive the restraining column 362 to move from the second end to the first end. During the aforementioned process, the second resilient component 365 is compressed, and the restraining component 361 retracts relative to the driving block 11 a, so that the driving block 11 a is allowed to pivot to the folded position relative to the base 20.

As shown in FIG. 23 and FIG. 24, the locking mechanism 35 includes the locking assembly 3 a, the abutting component 3 b, a third resilient component 3 f and the abutting block 3 c connected to the abutting component 3 b. The locking assembly 3 a is for engaging with the protective fender 31 to restrain movement of the protective fender 31. The third resilient component 3 f is for biasing the abutting component 3 b to disengage the locking assembly 31 from the protective fender 31 along a direction opposite to a direction K. The abutting component 3 b is driven by the abutting block 3 c to drive the locking assembly 3 a to the locking state for engaging with the protective fender 31, particularly the supporting block 13 a, when the abutting block 3 c is pressed downwardly. The abutting component 3 b is driven by the third resilient component 3 f to drive the locking assembly 3 a to leave away from the locking state to the releasing state when the abutting block 3 c is not pressed. In this embodiment, preferably, the third resilient component 3 f can be a torsional spring abutting against the abutting component 3 b and the base 20, and the locking assembly 3 a can be configured to move upwardly to engage with the protective fender 31. Furthermore, the locking mechanism 35 can be a seesaw mechanism, and the torsional spring can be configured to bias an end of the abutting component 3 b near the locking assembly 3 a to pivot downwardly. When the seat body 10 is installed on the base 20, the locking assembly 3 a is in the locking state for engaging with the supporting block 13 a of the folded protective fender 31 which is not in use. When the seat body 10 is detached from the base 20, the locking assembly 3 a is in the releasing state for allowing the folded protective fender 31 to pivotally switch to the unfolded state, which can prevent the situation in which the caregiver forgets to unfold the protective fender 31.

As shown in FIG. 24, the locking assembly 3 a includes the locking rod 31 a and the first recovering component 37 a. The locking rod 31 a includes the locking end 32 a and the connecting end, which is not indicated by any numeral. The locking end 32 a is for engaging with the protective fender 31 to restrain movement of the protective fender 31. A sliding slot 39 a is formed on the abutting component 3 b. A sliding column 38 a protrudes from the connecting end and passes through the sliding slot 39 a, and the first recovering component 37 a biases the locking rod 31 a to recover to engage with the protective fender 31. Specifically, the locking assembly 3 a further includes the block plate 34 a located between the locking end 32 a and the connecting end, and the first recovering component 37 a abuts between the block plate 34 a and the abutting component 3 b.

Operational principle of the locking mechanism 35 of this embodiment is provided as follows.

When the child car safety seat is not in use, the seat body 10 can be detached from the base 20, so that the third resilient component 3 f can drive the locking assembly 3 a to move downwardly by the abutting component 3 b to disengage the locking end 32 from the folded protective fender 31. Therefore, the protective fender 31 can switch from the folded state to the unfolded state by the resilient component 33, which can prevent the situation in which the caregiver forgets to unfold the protective fender 31.

When it is desired to use the child car safety seat, the seat body 10 can be installed on the base 20 to press the abutting block 3 c to compress the third resilient component 3 f and drive the locking assembly 3 a to move upwardly to the locking state. At this moment, the protective fender 31 which is not in use, can be operated to switch to the folded state and restrained by the locking rod 31 a, so as to save occupied space. Therefore, the protective fender 31 of this embodiment cannot be retrained by the locking mechanism 35 when the seat body 10 is detached from the base 20, which can prevent the situation in which the caregiver forgets to unfold the protective fender 31.

Please refer to FIG. 25 to FIG. 29. FIG. 25 and FIG. 26 are schematic diagrams of a child car safety seat in different states according to a fourth embodiment of the present invention. FIG. 27 is a diagram of the child car safety seat shown in FIG. 26 without illustrating the seat body 10 according to the fourth embodiment of the present invention. FIG. 28 is a partial diagram of the child car safety seat according to the fourth embodiment of the present invention. FIG. 29 is another partial diagram of the child car safety seat at another view according to the fourth embodiment of the present invention. As shown in FIG. 25 to FIG. 29, different from the child car safety seats of the aforementioned embodiment, the combining assembly 15 a includes the pulling plate 151 a and a first resilient unit 158. The first resilient unit 158 abuts between the pulling plate 151 a and the supporting block 13 a. A locking portion 159 is formed on an upper end of the pulling plate 151 for being inserted into a notch formed on the driving block lla and located between the supporting block 13 a and the driving block 11 a, so as to retrain the pivotal movement of the supporting block 13 a relative to the driving block 11 a by interference between the locking portion 159 and the notch. When it is desired to pivot the supporting block 13 a relative to the driving block 11 a, the pulling plate 151 a can be operated to remove the locking portion 159 from the notch to allow the pivotal movement of the supporting block 13 a relative to the driving block 11 a.

In this embodiment, the supporting block 13 a is pivoted to the driving block 11 a at a position near an end of the driving block 11 a away from the protruding portion 111 a, and the supporting block 13 a is aligned with the end of the driving block 11 a when the supporting block 13 a is pivotally folded relative to the driving block 11 a. In other words, in this embodiment, the pivoting shaft of the supporting block 13 a and the driving block 11 a can be different from the pivoting shaft of the driving block 11 a and the base 20. Therefore, the driving block 11 a does not protrude from the lateral surface of the base 20 when the supporting block 13 a is pivoted to the folded position relative to the driving block 11 a. However, in the third embodiment, the driving block 11 a protrudes from the lateral surface. Furthermore, in this embodiment, the restraining mechanism 36 is omitted. When the seat body 10 is detached from the base 20, the unfolded protective fender 31 can be driven by gravity to pivot to the folded state. Besides, similarly, the included angle between the protective fender 31 in the unfolded state and the lateral surface of the base 20 can be substantially from 90 to 145 degrees, and preferably, in this embodiment, the included angle between the protective fender 31 in the unfolded state and the lateral surface of the base 20 can be substantially 100 degrees.

Other structures of this embodiment are similar to the ones of the third embodiment. Detailed description for those structures is omitted herein for simplicity.

In summary, the present invention utilizes the lateral shock absorber disposed on the base to collide with a car body during a side impact collision for transferring a side impact to the base and away from a child sitting in the child car safety seat. Therefore, it can effectively reduce a risk of injury or death of the child due to the side impact and provide enhanced protection for the child. Furthermore, the present invention utilizes the locking mechanism to restrain or allow pivotal movement of the protective fender of the lateral shock absorber in the folded state. Therefore, it has advantages of simple structure and easy operation and is capable of providing a convenient way for a caregiver to operate the lateral shock absorber.
